Answer:
5 - x = 3 x = 2
Step-by-step explanation:
Area of part 1:A1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2Area of part 2:A2=length*width=(8+2)*1=10 ft2Area of part 3:A3=length*width=8*2=16 ft2
Total shaded area : A1+A2+A3=41 ft2Total area of the reactangle : A=16*8=128 ft2Total area of the nonshaded region : 128-41=87 ft2
Answer:
There is a 99% probability that at least one of the intervals will cover the true mean yields at their location
Step-by-step explanation:
In a 90% confidence interval of the mean of a population, there is a 90% probability that it cover the true mean of the population.
What is the probability that at least one of the intervals will cover the true mean yields at their location?
This is 1 subtracted by the probability that none of them cover the true mean yields at their location.
For each one, there is a 10% probability that it does not cover the mean. So the probability that both do not cover the mean is ![0.1*0.1 = 0.01](https://tex.z-dn.net/?f=0.1%2A0.1%20%3D%200.01)
The probability that at least one of the intervals will cover the true mean yields at their location is 1-0.01 = 0.99 = 99%.
